Dr David Humphreys

David Humphreys is an Associate Professor of Evidence-Based Intervention and Policy Evaluation. He joined the Department in October 2013, having held posts at the Institute of Public Health and the Institute of Criminology at the University of Cambridge. David is interested in understanding how aspects of the built and social environment can be changed to help improve health and wellbeing and reduce social and physical harms. Much of David’s research has focused on investigating the effects of large-scale environmental or social policy interventions. David is also interested in methodological aspects of intervention research, such as: the design of complex interventions (natural and quasi-experiments); the measurement of environmental exposures (using GIS and GPS data); and the synthesis of equity effects.

My research interests include:

  • Alcohol and drug misuse
  • Violence and injury prevention
  • Physical inactivity
  • Social inequalities in health and wellbeing
  • Methods for evaluating complex population level interventions
  • A cumulative meta-analysis of the effects of individual physical activity interventions targeting healthy adults
